Factory rubber differential bushings wear out and allow unwanted movement that lets the differential shift under load, hindering handling consistency. Prothane's polyurethane front differential bushing kit replaces those degraded stock pieces with firm, durable bushings that hold the differential exactly where it belongs on your 1999-2004 Mustang Cobra.
Polyurethane construction that outlasts rubber. Prothane's proprietary polyurethane compound resists oil, ozone, and heat that break down rubber bushings over time. The material stays consistent through temperature swings, maintaining the same geometry year after year rather than softening and sagging like OEM rubber.
Tighter differential location means better power transfer. Eliminating differential movement under acceleration and cornering tightens the connection between the drivetrain and the chassis. The result is more predictable handling, reduced wheel hop, and improved traction off the line.
Prothane Super Grease included. Every kit ships with Prothane Super Grease formulated specifically for polyurethane, applied during installation to prevent squeaking and extend bushing life.
Choose your color. Bushings are available in red or black to match your preference under the chassis.
